A boss 18 on top of the hous a detail'in the nature of an ele peripheral bosses bearing type characters designative of the months; the first'daytype ing l lforms a handle whereby the. frame may be depressed. The housing includes inwardly projecting lugs 19 best illustrated in-Fig. 6, against which the type'die plate 1G bears, and which constitute supporting members forrparts of the operating mech anism. v

The date wheel mechanism.

The date wheel mechanism includes 'a T transverse shaft 20 fixedly supported in said cover vplates 15. and forming a mounting for pawl frame members21. rotatably mounted thereon, and which'are connected by'a top frame member 22. The type wheels include a month type wheel 24:, day type wheels 25 and 26, and ayear type. wheel 27. ,These typewheelsare independently rotatable on shaft 20, and each has conjoined to it ratchet wheel, that of the'month type wheel being designated 24, that of the first day type wheel 25, that of the second day type wheel 26" and that of the year type wheel The month type wheel carries twelve wheel carriesthree series of the characters blanks; the second day Wheel carriesa series of type characters comprising thenumerals i to 9 inclusive and 0,? while the year typ wheel carries type characters indicativefof V the years. The position of thelshaft 20, and

theiradius of the several type wheelsyjare; such that these type charactersgmayflbe brought into register with slots in the type die 16, so that-in their lowermost positions incident to rotation of the type wheels, their faces will occupy ,thefsame plane as the' faces of the printing type on the type die, and so that they may cooperatev with the,

T1. 2 and 3, the series being interspaced by platenin thesa-mefashion as the type of the type die.

type wheels are designated throughout by the numeral 28. Rotatably mounted on the The type embossmentsof the pawlframe members 21 .is a controlling cam I shaft 29carrying a plurality of cams d'esi'g uated respectively 30, 31, 32 and The contour of these several cams ,is identical,.

7 As a means forindicating the location of theribbon as between the two ribbon shafts,

' aitelltale device is provided, the same constituting a stub shaft 71 'rmnntedv in the right hand side cover plate and carrying at its outerend a pointer 72 and at its inner end a lever-74 adapted to rest-upon the ribbon wound on the front. ribbon shaft, nn- I der the pressure of a spring ie. Indicating graduation's are provided on :tll(.'l(ltfi cover plate in associationwith the pointer 72,from V which the approximate proportion of the" ribbon wound on the forward ribbon shaft 7 may be determined, 'sothat the reversal of feed by adjustment of the pinion 6421s abovedescribed may be made at proper times.

As a means for determining by convenientinspection what type characters of the type wheels are in printing position, the wheels are provided with indicators .76. preferably printed on white celluloid or the likexand mountedbetween the type bosses at siich'angular relationship to'the several type characters as to be readable through an inspection opening '77 in the front of theho'nsing when corres ondin characters are )resented at the printing position. i M

It is believed that the operation of the several parts of the device has been made clear in the foregoing, so I will here describe simply certain operations in their. general or cooperating. relationship. vIn the setting up of a date, the control camshaft 29 isrotated to proper position, as may be observed from the le endson the head 36 to" engage a selected type wheelffor example,

' the month type wheel. The pawl frame-'21 is then swung forwardly by pressure on the. I head-36, advancingfthe month type wheel one step. This is repeated untilthe proper month type boss is presented at't-h'e printing position. The control cam shaft is then shiftedv to engage, say, the first day wheel,

\ and the pawl frame oscillated as many times ing impression up.

as may be necessary to move the properftype boss to position. control cam shaft; and oscillation of. the

pawl frame is effected to properly position the second day wheel and the year wheel.

The sheet'upo'n which the printing impres s'io'n islto be made is then laid upon the" platen, with the portion toreceivethe print- The operator may thus accurately position the sheet which jhedeeffected at the "place desired; The sewing? ing frame 2 is :then swung downto make impact uponthe sheet'on theplaten, and the printing-is efiected through the ribbonby the type of the printing die plate: and of the I Incident type bosses in printingz position.

Similar shifting of the sires tostamp, s that the printing may be 5 to'the downward movement ofthe swinging frame, the ribbon: feed link-.55 is shifted inwardly,*thiis rotatingtheswinging plate '58 and carryingthe feed pawl 59' forwardly .over the ratchet wheel 60. :Up'on the res lease of th'eiswinging frame, itis raised the I'influencexot spring, 8, vincident towhich movement the rearward shifting of link 55 rotates pinion 64 byvirtu'e of the engage- -ment of fee'd'pawl'59 with ratchet wheel 60.. 'I

This movement is transmitted through eitherpinion 53 51: 53 with which pinion" Get-is Imesh, a-ndythe ribbon is ted by: the consequent rotation of the actuated ribbon "shaft.

sheet'accnrately on the platen so that the impression may be stamped exactly where he desires it. Thefashionof mounting and "operating the type Wheels provides'a very compact structure which does not render the head of the machine unduly lar e,;and at the same time secures accurate aligning andsecnrity against over-'throwiincident to violent operation of thedevice: The-rota 'tion of the type wheels in themanneridescribed permits the utilization: of "a very 7, heavy detent' spring for holding-and aligni'ng the type,.-as the leverage between the 'hea d 36 and fthesha'ft 20 is snfiiciently long to render theintentional operation of the wheels quite easy. The mechanism is easily.

assembled, and the printingjtype die may;

be removed and replaced independently or other parts. Pressures received bythe type, wheels incident to making an mpression are transmitted to the substantial type wheel shaft. '20, which virtue of the act that it may be a solidshaft, particularly adapt; edto sustain them, all of the setting and re taining' mechanism for, the type. wheels being entirely relieved 'from these pressures The, ribbon feeding mechanism is compact and simple, and is operated incidentfto the use of the stamp, for .feedingthe ribbon in either direction.' v
